Description

The objective of this technique is to allow users who cannot hear to be able
to access real-time synchronized media broadcasts. It is more difficult to create
accurate real-time captions because there is little time to correct mistakes
or to listen a second time or consult someone to be sure the words are
accurately reproduced. It is also harder to simplify or paraphrase
information if it is flowing too quickly.

Real-time typing text entry techniques exist using stenographic and rapid
typing technologies. Re-voicing speech-to-text (where a person listens to
speech and then carefully re-voices it into a computer trained to their
speech) is used today for telephone relay services and may be used in the
future for captioning. Eventually speech-to-text with correction will be
possible.

Examples

Example 1: A television studio uses a real-time captioning service
to create captions for its evening news online.
